PIRN OR COP WINDING MACHiNERY.

SPECIFICATION forming part of Letters Patent No. 236,300, dated January4, 1881.

Application filed April 5, 1880.

To all whom it may concern Be it known that we, 'JOHN BOYD and THOMASALEXANDER Born, subjects of the Queen of Great Britain, and residing atShettleston, in the county of Lanark, Scotland, have invented certainImprovements in Pirn or Cop Winding Machinery, (for which we obtainedBritish Letters Patent dated June 27, 1873, No. 2,226, and December 1,1874, No.

4,119,) of which the'following is a specification.

' Our invention relates to the winding ,of yarns on pirns or in cops, tobe used in shuttles or otherwise, and to machinery of the kind :5 inwhich, on the winding of a pirn or cop being completed, an automaticseparation of the pirn or of the cop-spindle takes place, so that itbecomes disconnected from its driving part and its motion is stopped.The machine is made for winding horizontally-placed pirns or cops at itstwo opposite sides, and the windingspindles of one side alternate withthose of the other side, and their inner or back ends project across, insome positions, nearly to the other side of the machine. To prevent thesaid inner or back ends of the opposite and alternate spindles frominterfering with the pirns or cops at either side, certain curvedplatesor shields are provided to cover the spindle ends and their brackets,and to form troughs under the pirns or winding ends of the spindles, tocatch the full cops as they are pushed oft the end of the spindle. Theseries of alternate winding-spindles which extend 3 5 horizontallyacross the machine are carried by two parallel rails near the middle ofthe machine, and aredriven by a longitudinal shaft placed just abovethem, and carrying a driving bevel-wheel for each two spindles, everysecond spindle receiving motion through spurpinions, the main object ofpassing the alternate spindle through the same two rails andconstructing the parts in the manner described being to reduce the widthof the machine.

Figure 1 is a transverse vertical section of a pirn or cop windingframe, and shows the several parts combined together. Figs. 2, 3,

and 4 are enlarged detached views of the fixed bracket for the weightedlever; Figs. 5 and 6, views of the compensating-lever for the (Nomodel.) Patented in Great Britain June 27, 1873, and December 1, 1574.

The main framing of the machine consists of transverse vertical frames20, connected by two inner longitudinal rails, 21, near the middle andan outer longitudinal rail, 22, along each side. The winding-spindles 23are placed horizontally and transversely, and pass through the innerrails, 21, those appertaining to one side of the machine alternatingwith those appertaining to the other side.

In Fig. 7 two winding-spindles, 23, appertaining to one side, are shownalong with a part of an intermediate spindle appertaining to the otherside. The winding-spindles 23 pass through bearing-bushes screwed intothe inner rails, 21, and through driving-tubes 24, which are heldbetween the rails, and are formed with spur-pinions 25, while eachalternate one is also formed with a bevel-pinion, 26.

The driving motion is communicated by a central longitudinal shaft, 27,which has on it a number of bevel-wheels, 28, there being one for eachpair of spindles. Each bevel-wheel 28 gears with the bevel-pinion 26 onone of a pair of spindle-tubes, 24, and the motion is communicated tothe other of the pair by the 0 spur-pinions 25. The tubes 24 drive thespindles 23 by means of slots, into which keys or feathers on' thespindles project, as shown in cross-section in Figflb', this arrangementallowing the spindles 23 to move endwise through 5 their tubes 24 whilebeing made to rotate by the tubes. I

On the inner or back end of each windingspindle 23 there is hung aswivel-piece, 29, (shown detached in side elevation in Fig. 10.)

The spindle is made with a shoulder and a reduced end, and when theparts are put together a nut, 30, is screwed up to the shoulder, thisnut occupying a recess formed for it in the swivel-piece 29. Theswivel-piece 29 is bored so that its outer part its loosely on thereduced end of the spindle and its inner part on the unreduced part, andpressure between the spindle and swivel-piece acts on the end of thespindle when in one direction and on the inner face of the nut 30 whenin the other direction.

The swivel-piece 29 is formed with lateral indentations, in which fitfreely prongs 31 ot'the forked end of a slide or movable bracket, 32,(shown in plan in Fig. 13 and in side elevation in Fig. 14.) Thismovable bracket 32 has jointed to it a weighted lever, 33, (shown inplan in Fig. 11 and in side elevation in Fig. 12,) and the two work. inconnection with a stationary bracket, 34, which is shown in plan in Fig.2, in side elevation in Fig. 3, and in end elevation in Fig. 4, andwhich is bolted up to the under sides of the inner rails, 21. Themovable bracket 32 is supported and guided on guides 35 36, formed forit on the ends of the fixed bracket 34, these surfaces, which areshownin section in Fig. 1,allowing just enough room between them and theunder sides ofthe rails 21 for the easy movement of the movable bracket32. After the movable bracket 32 is placed in position, aretaining-piece, 37, is screwed to the fixed bracket 34 at one (36) ot'the guide-surfaces, to preventits displacement. The back end of themovable bracket 32 is formed with a turned-up forked part, 31, whichembraces the swivel-piece 29 on the inner end of the windingspindle 23,as hereinbefore indicated, and the other end is formed with a horn, 38,which passes up at the side of the shield 39, and serves as a handle formoving the movable bracket 32 by, and by the connection at the inner endmoving the windingspindle 23 also.

The weighted lever 33 is, by one or other of a series of holes whichadmit of the connection being changed to suit different lengths of pirnor cop, jointed to a downward projection, 40, on the movable bracket 32,near its inner end, and apart of the weight-lever works between aslotted or double part of the fixed bracket 34, projections 41, formedon the opposite sides of the lever, resting on the upper edges ofthedouble partofthebracket. These upper edges of the double part of thefixed bracket 34 are inclined in opposite directions from a high point,42, which is nearone end, and while the winding of a pirn or cop isproceeding the weighted lever 33 rests on the longer incline. As thegradual accumulation of yarn on the pirn or spindle forces back thewinding-spindle 23, and with it the sliding bracket 32, the weightedlever 33 is drawn up the long incline, its weight and resistance to thatmovement serving to press the pirn or cop to the desired extent into theconical cup 43, which isemployed, as usual,toimpart compactness ordensity to the yarn as it is being wound. As soon as the projections 4Lot' the weighted lever 33 reach the highest point, 42, of the inclines,they proceed to pass down the short incline, and then the tendency ofthe weighted lever is not to resist the backward movement of thewinding-spindle 23, but to make it move back, and this causes thewinding-spindle to become separated from the pirn or cop spindle, thefurther inward movement of which is prevented by a stop, as hereinafterexplained. It will thus be understood that the length of pirn or copwound is determined by the extent of the inward movement of thewinding-spimlle 23, which takes place from the commencement of thewinding action until the highest point, 42, of the inclines is reachedby the weighted lever 33.

The conical cups 43 are fixed to the outer longitudinal rails, 22 andthe traverse guidefingers 44 are fixed to rocking ried inside the outerrails, 22, and worked by means of levers fixed on them and connected toan eccentric on the longitudinal shaft 27.

The yarn to he wound is shown as proceeding from a reel, 46, on one sideof Fig. l, and from a bobbin, 47, as shown on the other side, up to acompensating-lever, 48, which is shown separately in plan and sideelevation in Fig. 5. The movement of the compensating-lever 48 islimited by horns or projections near its pivot, these encountering aboss on the small bracket in which the pivot or center-pin ofthe leveris fixed. A wire spring,-4.),is coiled round the center-pin and bears ona projection on the lever4S,this spring causing theleverend,which has aguide-button, 50, on itfor theyarn to pass round,to rise when the yarnis being wound on the smaller end of the cop or pirn surface, andallowing it to yield downward when the yarn is being wound on the largerpart, and thus tending to equalize the rate at which the yarn is drawnfrom the reel 46 or bobbin 47. With some yarns of a slippery and elasticnature the compensating-lever 48 has not suificicnt control when tittedwith a single guidebutton 50, and in such cases we provide it with twobuttons 50, as shown in plan and side elevation in Fig. 6. The yarn canbe led round the two guide-buttons in various ways, accordingly as moreor less tension or control is in practice found necessary. In Fig. 1 thecoinpensating-levcr 48 at the right-hand side is shown as titted withtwo buttons 50.

Each winding-spindle 23 has fixed on what may be termed its frontend aclutch-disk, 51, (shown separately in Figs. 16 and 17,) having on itsfront face two tapered clutch projections or teeth, 52, adapted foreasily engaging in counterpart recesses in a disk, 53, (shown separatelyin Figs. 18 and 19,) which has fixed in it a spindle, 54, for windingcops on, which spindle is afterward withdrawn from the cop.

When winding on pirns, the pirn-bottomsare formed with recesses toengage wit-h the clutchshafts 45, carteeth 52; or pirn-holdersconsisting of spindled disks like that shown in Figs. 18 and 19 may beprovided.

The troughs or shields 39, as shown in Figs. 7, 8, and 9, consist eachof a thin metal plate, 39, fixed at its outer and inner ends,respectively, to an outer and inner rail, 22 21. This plate 39 is curvedso as to pass over the inner end of one winding-spindle 23 and under thefront end of theadjacent winding-spindle, and the part passing under thefront end of a winding-spindle has a slot formed in it, (indicated bydotted lines in Figs? and 9,) in which there is fixed a stop, 55, toarrest the disk 53 when the winding-spindle 23 is drawn back at thecompletion of a pirn or cop, as hereinbefore explained, this stop55-being adjustable to suitdifferent lengths of pirn or cop. \Vhen thepirn or cop is thus pushed off the windingspindle it is caught by thetrough, instead of being allowed to fall down through the frame, whereit might cause a stoppage of the machine or a breakage of some part.These troughs also serve, with their overhanging portions, to preventinterference between the front ends of the winding-spindles 23 and thecops on them and the inner ends ot'the adjacent spindles from the otherside of the machine. Thereis also'a slot in the other part of theshield, to give access for oiling the swivel-piece 29.

We claim as our invention in pirn or cop winding machiuery 1. The framehaving two inner rails, 21, the slotted tubes 24, geared together inpairs, each alternate tube having a bevel-wheel, and a longitudinalshaft having bevel-wheels geared therewith, in combination withwinding-spindles 23, passing through the same two rails altern ately toopposite sides of the machine, and having keys or feathers adapted tosaid slotted tu es, all substantially as set forth.

'2. The combination of the main frame and driving mechanism with fixedbracket 34, weighted lever 33, movable bracket 32,-and winding-spindleadapted to move with but turn independently of the said bracket, allsubstantially as set forth. v

3. The combination of the main frame, winding-spindle, and drivingmechanism with the movable bracket 32, adapted to guides on the frame,the swivel-piece 29, weighted lever 33, and fixed bracket 34.

4. The combination of the frame, winding mechanism, and winding-spindlesadapted to slide longitudinally in the frame, with stops 55 and troughs39 below the ends of said spindles, to catch the pirns or cops as theyare pushed off the ends of the spindles, substantially as set forth.
